Brakes !!!!! What am I doing wrong ?

[Roidfingers]

Installed new brake lines. Everything has gone very smooth. But now I can't get either front brakes to bleed. Even pulled the speed bleeders out completely. Help Please !!!!!!!

[Motorider]

So nothing happens when you pump the brake handle. Is that correct?

[Roidfingers]

Have every thing tighten and torqued. Have hose on left caliper speed bleeder. Other end in catch jar below fluid level. Resevoir is full. I pumped the brake lever but get no pressure and no air bubbles.

[bassman]

Any chance the brake lines came with some type of dust / dirt plug to keep junk out until installation and needed to be removed prior to install?

[Roidfingers]

I cracked open the banjo bolt and I seemed to get a little fluid out. Just a drop every 20 seconds or so. I read somewhere that the speed bleeders don't work if you have to much air in the line. Not sure I get that. Pressure is pressure.

Is the above correct???

[Roidfingers]

Yes. Nothing happens. No pressure no air bubbles. Nothing. Resevouir still at same level

[Valker]

Speed Bleeders ONLY work with lines that are almost full of fluid. A vacuum pump is the best way to fill the lines.

[Roidfingers]

Valker is there an inexpensive one out that that works good?

MityVac.

About $30 at AutoZone or similar automotive parts places.

[Roidfingers]

Got this one and its metal.

I use a Mity Vac also. I try not to buy the metal ones as my hamfisted self tends to bend things like that so they no longer seal.

I think you right about the bleeder valves. If I loosed the banjo, I can get a little fluid to it. But wont get much I guess when its sucking air back in. But get nothing with them tight and bleeder open.

[hubcapsc]

When I have the system all the way dry, I take out the speed bleeders, and screw
back in the original bleeder. There's a short hose and a big syringe hooked
to the original bleeder, so I suck some fluid down into the lines. Take out
the syringe bleeder and put back in the speed bleeder, and then stuff starts
working. Some fluid usually escapes during the bleeder changeout,
careful what you get it on... clean it off real good...

I thought about that hubcap. but looked all over and could night find my oems. Dang it.

Your system is full of air, the master cylinder is air locked, you can let it self bleed the drip, drip, drip or use the vac pump. Operating the brake lever with air trapped will usually never exhaust the air. If you let it drip or vacuum it make sure to keep the master cylinder full, the brakes will finally bleed out the air.

[Roidfingers]

Yea Firefighter. Doing the gravity drip thing now. Gonna go by auto parts place tomorrow and see about a bleeder valve as I wait on my vacuum kit to arrive. No hurry. Weather changed and I wont be riding for at least a week.

[Firefighter]

Sometimes they will drip until the air clears and then start a more steady flow.

Roid, I had a HF vacuum didn't last very long.

[Roidfingers]

Thanks for the info all. Ken, I just need it to last once. LOl I hope.

I have a Craftsman metal vacuum pump which is used for such things as diagnosing petcock issues or providing a source of vacuum to drain the tank with the engine off. The plastic MityVac is only used for clutch and brake bleeding chores. For that it works well, and is cheap to replace if stepped on.

Just for interest. I did my fronts a different way. Used two large syringes, and two plastic tubes. Syringes full of brake fluid, connect tubes to bleeders, tops off reservoirs, pump fluid up both lines until reservoir full. No need for bleeding. I didn't. There's videos on Utube showing basically how.

IIRC, MotionPro and at least one other vendor marketed such a system that drew fluid up through the bleeders and lines by way of a vacuum pump and matching master cylinder cover.

I'll see if I can find it. Were I still involved in the powersports industry as a paid participant, that thing would definitely be in my toolbox.

If all else fails, how about installing the original bleeders and try it the old fashioned way just to see what happens.

ElvisThe OEM bleeders hashave left the building, methinks...

[Roidfingers]

  Yes they have ! Gonna go try to pick one up at auto store. If not. my vacuum bleeder will arrive tomorrow.
